Application classes

Description
There are different application classes for PROFIdrive, depending on the scope and type of
the application processes. PROFIdrive features a total of six application classes, four of
which are discussed here.
Application class 1 (standard drive)
In the most basic case, the drive is controlled via a speed setpoint by means of
PROFIBUS/PROFINET. In this case, speed control is fully handled in the drive controller.
Typical application examples include simple frequency converters for controlling pumps and
fans.
